How Weather Satellite images are decoded

About the Enhancements

This page shows just some of the 35 enhancements WXtoImg provides:

MSA

Multi-Spectral Analysis: combines a sensor 1 or 2 (visible/near infrared) image with a sensor 4 (thermal infrared) image to create a near true colour, near visible image of the earth.

MCIR-precip

Map Coloured IR with Precip: uses sensor 4 (thermal infrared) to create a false coloured image showing areas of likely precipitation. The likelihood and intensity of precipitation increases as the colour goes from green to yellow to orange to red to black to white.

HVCT

HVCT false colour: creates a false coloured image by combining a sensor 1 or 2 (visible/near infrared) image with a sensor 4 image (thermal infrared) to create an image in which clouds are tinted by their temperature.

Pristine

These are images as they come from the satellite without alteration. The earth appears "upside down" on Northbound passes. The two images are the two channels sent by the satellite with channel A (left) switching between sensor 1 (visible) or 2 (near-IR) during the day and sensor 3 (mid-IR) at night and channel B (right) showing sensor 4 (thermal-IR) at all times during normal operation.

Thermal

Thermal: Creates false color images using the temperatures from (sensor 4) Thermai Infrared image. This sensor covers the full range temperatures from very cold cloud tops to very hot deserts.

SST

Sea Surface Temperature: creates a false colour image by combining sensors 3 and 4 (Infrared) and using a pre-defined palette colour the image.
